Great information for beginners, and someone like myself. 20+ years ago I was building custom enclosures, been a while. I'm getting back into car audio, and the game has changed.

[@DIYAudioGuy]

Share with the next generation so we can save them from buying a crappy box.

[@michaelbloom5342]

>the game has changed That's not true at all. The physics are the physics, the math is the math. That has not, and will never change. The only thing that's changed is people now *ignore* the math, and then wonder why their stereos sound like crap. The consumers have simply become ignorant. Worse than that, willfully ignorant. If 20 years ago, you'd ask your average stereo consumer what Thiele-Small Parameters are, and thanks to the magazines like Stereo Review, Car Stereo Review, Car Audio & Electronics, and even Auto Sound & Security, everyone would at least have an idea. The magazines really did try to educate the consumers. All that is gone now, and if you ask someone today about TSP's, they look at you like you're from Mars. This despite having all of the knowledge in the world right at their fingertips.

[@BobBasshead]

@@michaelbloom5342 You hit the nail on the head! I got into this hobby back in 1985. Your absolutely correct about the reading material on hand with good solid guidelines explaining articles such as Thiele-Small Parameters, but unfortunately math was my downfall. My first installation was in my 1978 Chevy van with four Pyle 10" in a custom box between the wheel wells, sized as per Pyle's recommend volume and port size. I didn't have the money to buy a new amp so I scored two well used Rockford Fosgate four channel amps (50 watts RMS per channel) specs that I got from Car Stereo Review buyers guide. One of them didn't work. Having a electronics background I was able to repair that amp. Problem? The turn on transistor was missing, the turn on wire wasn't like the one used on today's amps, it had to sense a current draw. RF said to connect the positive wire from the head unit to create a current draw. Then I had to figure out the 5 pin din connector they used to power the dashboard mounted equalizer to RCA connectors. I purchased a Kenwood CD player ($600) with no radio. They just came out on the market, unfortunately it skipped every time I hit a bump in the road. I took it back to Crazy Eddys three times and they couldn't fix it. So I demanded a new unit and by then it included a radio module. Sorry if I went off on a tangent, I could go on and on....

[@BenaresDarkness]

@@michaelbloom5342 Well you are wrong about that it has changed since the 90s or the 80s and it always continue to change due to it improving.

[@michaelbloom5342]

@@BenaresDarkness The one and *only* thing that has gotten better is the digitalization of processors. And even then, a lot of that is wasted, because trying to find a head unit with digital outputs is difficult to say the least. In the 90's, pretty much every single high end head unit had TOSLINK out. Try to find that now. The vast majority of amps today are far, far worse than what we had in the 90's. The slew rates have gotten so bad, the manufactures won't even list that value in their specs anymore. And don't get me started on reliability. Most of today's amps are made in Communist China by those poor souls making 2 cents per day, using the absolute cheapest possible parts. They're almost universally junk. The amps we got in the 80's and 90's were all handcrafted in the USA (mostly in Arizona), using the highest grade parts available, populated on Mil-Spec circuit boards. Each and every *individual* amp was bench tested to assure it *exceeded* factory specs. Then, Rockford went one better, they physically beat on each and every single amp they made with a rubber mallet, just to make sure they would hold up. This is the reason that an amp bought 30 years ago still works to this very day.

I just bought a Concept Enclosures 15" sub box on eBay for my 15" Skar Audio SVR-D4. 4.25 cu ft, 6" front firing port, birch plywood (two layers on the front!). Tuned to 32 Hz. All for under $350 (they let you customize it before ordering). Been doing car/home stereo since the early 1980s. This sub box is incredible...the output is insane. I agree...most of the cheap crap on Amazon isn't worth the cardboard they are packed in. You want deep bass...having more space & tuned porting by pros that know what they are doing is KEY.

Did you happen to check the cutout size first? The T1 is a bit oversized. If you need to make the hole bigger start by trimming back the carpet before you grab your jig saw.

[@_BAD_MERC_]

I worked for 9 year at a custom shop and we didn't use MDF, we used Trupan Ultralight and it was a pleasure to work with. The sawdust was like talc and the density was higher but the material was measurably lighter. I always painted bare wood and the inside of enclosures to prevent material "breathing". Have any of you used or tried this material?

[@murrayshekelberg9754]

I have the single 12" of the Skar box and was really impressed with it overall when it arrived. Its solid and has a nice kerfed port and the bit of overhang above and below the speaker mount help provide a bit of clearance/protection to the speaker when I need to slide the seat all the way back. I have it in a 90s model extended cab Ranger. It fits with room to spare if you have a Ranger/Mazda Bseries extended cab and were wondering. I couldn't find any info online when I ordered but assumed it would fit one way or another. I could probably fit 2 sitting regular or if I stood them on their side I am almost certain 3 would fit, maybe 4. It stands on its side and stops an inch or two below the rear window which presents some interesting possibilities. The wires are a bit short but manageable and easily replaced if need be. I have had 3 different subs in it with not issues connecting the wires.

[@DIYAudioGuy]

Thanks for the videos man. I always enjoy them. Q-Logic used to make some really solid prefabs way back when, but I think they quit. Or got bought out.

[@DIYAudioGuy]

I just hate to see people spend their hard-earned money on a box for 2 12's made out of 5/8 MDF.

[@motoman22atgmail]

I got one of those cheap 5/8 prefab dual 10” center-vented boxes for free (exactly like shown at 0:48) I measured and it was 2.5’ cubed internal vented space (raw) with a huge port. The tune was calculated right about 48hz. Safe for most subs but FAR from what I wanted. To get a 36hz tune it needed less port area for the set port length. I reduced the port floor and ceiling distance with scrap, closed off the voided port area front and back, and wrapped it in a layer of 1/2” for rigidity. A free box, a few hours of calculations and cutting/gluing scrap = DEEP bass that sounds great. It can be done if you don’t have time to start from scratch.

[@DIYAudioGuy]

That is awesome!

[@theejoeylee]

Actually tuning high is not safe at all for most Subs... because what happens below tuning is the driver acts like it is in free air...The port is no longer resonating, so the port is essentially just a hole in the Box below tuning. This unloading of the driver can cause ripped spiders ,surrounds, or damage to voice coil from smacking the backplate

Thank you for posting this. I actually bought one of the SKAR boxes after watching this video. Given my lack of knowledge, I bought a dual voice coil 2 ohm subwoofer.

Thank you, for all of your wonderful information.

[@DIYAudioGuy]

8 gauge is huge for speaker wire. Consider smaller wire. You can also grit some crimp connectors and crimp two wires onto one wire and then just connect that single wire to the terminal.

[@seanyounk1]

@@DIYAudioGuy I was referencing a chart with 1200 watts rms / .75 for amp efficiency / 13.8 volts. the chart shows 115 amps requires 8 gauge wire. Am I doing something wrong?

I got a prefab box from Parts Express super cheap that was for a single 10-inch ported. I cut the slot Port out of the bottom, cut the carpet off the baffle and glued another one on top, then I cut a hole for an 8-inch skar audio subwoofer and put in a 3in round port and it absolutely hammers.. astounding output down to about 32 Hertz. Way louder and lower than the 10-inch sub I had in it when I got it. I believe the slot Port was tuned to 50 hz !

My biggest beef with a prefab is that they tend to be undersized and tuned too low.

[@theejoeylee]

@@DIYAudioGuyyou mean too high.. That's why I went up a box size and put a new baffle on, with a traditional port. Like if you need a box for 12 get a prefab for a 15 and put a new baffle on.

@@DIYAudioGuy yeah I could tell the one in the video had a shorter port.

Everyone keeps saying the baffle is weak, but it seems like bolting a lipped steel ring (the speaker) to the hole would stiffen it quite a bit. It would be interesting to see someone run some boxes with air pressure in solid works to get a better (real) idea of where bracing needs to be. Everyone seems to add 45s to corners and other stuff but placement always seems random and many cases where I know a simple horizontal gusset would be more effective

I was not impressed at all with my Atrend Ram 1500 "B-Box" from Amazon. I complained and they gave me a partial refund. The pictures showed a nice, metal, push to connect speaker terminal. On the actual box was a cheap plastic thing that couldn't even fit 12 gauge wires, so I had to change that. #2 The "caulk job" was very sub standard, so I had to re-seal it. #3 It specifically said and showed that it came filled with poly fill. It arrived empty, so I had to run to the craft store. I normally build my own enclosures, but the one for the Ram Crew needs some really complex shapes.

[@DIYAudioGuy]

When I was researching for this video I noticed that the price had DOUBLED compared to what I paid for mine,and like you said the pics showed poly-fill and better terminals. For double the price, hell no. Especially if you don't get the upgrades. But for what I paid it was just fine to get me started. My goal was always to fiberglass a box, that is happening this summer.

Got a skar evl-12 i just bought. Looking for a sealed enclosure but most everything out there is ported these days😫😫. Some good quality brands but nothing for a single sealed box @ 1.75 sq ft.

Try building your own. Home Depot can cut the boards down for you if you don't have a saw.

We had a local audio shop years (pre internet) when i was a wee aspiring audiophile who when i would ask 'hey what about this sub in this box? Oh yeah yeah, that'll bang. 'Oh ok, well what about that sub in that box?' Oh yeah, that'll bang. I bought a couple of sub, prefab box combos from that guy and they all sounded terrible. Ended up buying a single 12 infinity from circuit city and it was great. Anyhoo, this video just jogged my memory. Box size DOES matter. Wood thickness as well.

Im wanting to build a budget system using 6 skar 12s. Im looking at using 2 skar pre fab ported triple 12" boxs with 6 skar svr subs. In your opinion, should i stack the boxs and fire them forward or backwards, or lay them on their backs and fire both up? I dont have the time and effort to build a wall or box big enough and i know the Skar box is built and tuned well for that sub.

[@DIYAudioGuy]

Since you can just move boxes around you can try them each way and see which one sounds best.

[@joshuakemp1439]

When i get my custom enclosure in next few weeks ,i would like to some how get the SK2X12V enclosure to you for testing. I dont believe its 2cuft per chamber. It might be tuned at 32 but can hear chuffling on low notes around 30hz. Took few orders to get one not damaged because skar dosent secure the box.they only use a plastic bag and cardboard. Main concern is the box isnt up to specs. Lots of products from skar have multiple spec contradicting each other. For example vxf 12s says one thing on website and the manual say completely different.

[@DIYAudioGuy]

Shipping cost make that impractical.

[@joshuakemp1439]

I know you can measure the inside but i dont know the formula or which one to use to determine the exact amount of space. Your right about shipping thats crazy prices.

[@DIYAudioGuy]

I'm indifferent, some of them are trash some of them are fantastic, some of them are overpriced. If you don't have the tools and the time to build your own box go ahead and buy one.

[@pigebear]

Would you recommend Skar for a single 12 application?

[@DIYAudioGuy]

I always recommend a custom box made for the speaker. I don't pay much attention to brand names, instead I try to focus on how it is built. When I made this video the Skar box was the best I could find on Amazon.

[@bytsky2506]

This is hilarious because I have the Skar 10" dual subbox. It could have been built a little better though. Fabric could use some work

I just installed a new jvc kd-x270bt, new 4x6's in the front and new 6x9's in the rear. Front works great but hardly any sound coming from the rear. Could you give me some advice on what I need to do to get the rear as loud as the front 🤔

[@DIYAudioGuy]

It is hard to troubleshoot in the KZbin comments. My first guess is you have the polarity swapped on one of the rear speakers and they are canceling each other out. So start by double-checking your connections. and swapping the polarity on one of the rear speakers. You may need to grab one of these: amzn.to/3sVIU8i Other than that and going through all of the settings (EQ, crossover...) on the head unit I can't offer much more advice.

[@scorpion30001]

Hi there i would like to know how to identify which subs play lows well and which plays higher frequencies well. What ts parameters will indicate that or can any sub play any frequency.

[@DIYAudioGuy]

People usually claim that, holding everything else constant, a subwoofer with a lower resonant frequency (FS) can more easily hit low notes compared to a sub with a higher resonant frequency. But what really matters is the performance of the subwoofer in the enclosure. For that you want to look at the f3.

Hey that is a great subwoofer. Sundown recommends 1 cuft tuned to 35 HZ, so just look for a well-built box with those specs. But for a nice sub like that it really deserves a custom built box.

[@Ronco160]

I'd personally buy the $119 dual-port, separate chamber box on amazon made by American sound connection sold by hi-fi sound connection. great tuning hz in the 30's built with 3/4" mdf. plenty of port for each sub. Skar box specs on internal airspace are before port displacement.

[@DIYAudioGuy]

I will have to look that one up!

[@OGmudbone865]

Bro, if you have a Dyno, you should just do a string of videos testing a bunch of different subwoofer ratings. There's a few, here & there, but no one has more than 2 or 3 brands. Like Derek Willingston has tested probably 100 or more amps, that's kinda his thing. Couple subs, but still, not very many. Someone needs to do subs like he does the amps. Big boy gang moves.

[@DIYAudioGuy]

That would be fun!

[@thatguy_jose]

What are your option on the kicker manufacturer box for the older style L7

[@DIYAudioGuy]

Kicker knows what they are doing. A manufacturer boxed matched to a subwoofer is designed for mass market appeal. So it may not be the right box for you, but it is the right box for 80 to 90 percent of the people that buy them.
